RESUMO
Objective To explore the clinical features and endoscopic manifestations of eosinophilic gastroente-ritis(EG)in children.Methods A retrospective analysis was conducted of the clinical manifestation,laboratory examination,endoscopy(upper and/or colonoscopy)performance,diagnosis and treatment of 49 cases of patients who were diagnosed as EG in Children's Hospital of Nanjing Medical University from July 2013 to July 2015.Results The common clinical manifestations of EG in children were hematochezia(23 cases),diarrhea(20 cases),vomiting(18 cases)and abdominal pain(15 cases).The ages of children admitted to hospital for the first time ranged from 1 month and 7 days old to 13 years and 7 months old,and the mean age was 59.4 months old,in which most patients were younger than 1 year old,accounting for 38.77％(19 cases)of all.Peripheral blood eosinophilia was present in 20 cases(40.82％)of the patients,and only 6/18 cases(33.33％)of the patients had elevated serum IgE.Upon endoscopic analysis,the lesions involved esophagus(4 cases),stomach(14 cases),duodenum(20 cases),small intestine(15 cases),colon(28 cases)and rectum(6 cases),and the most common manifestation under gastroscopy was mucosal hyperemia edema(27 cases)and erosion(9 cases),while the most common manifestation under colonoscopy was mucosal hyperemia edema(25 cases)and nodular hyperplasia(24 cases).All patients improved with food restriction,in which 8 cases were treated with glucocorticoid while 9 cases with oral Singulair and 9 cases with oral Loratadine.All children with symptoms were alleviated somewhat,but 5 cases of them relapsed after drug withdrawal.Conclusions The clinical manifestations of EG in children varied and were mainly hematochezia,vomiting,diarrhea and abdominal pain.Some patients had the elevated peripheral blood eosinophilia and serum IgE.The most common manifestations under gastroscopy were mucosal hyperemia edema and erosion while the most common manifestations under colonoscopy were mucosal hyperemia edema and nodular hyperplasia.
RESUMO
Objective To explore the effect of particulate matter (PM) 2.5 on the expression of pigment epithelium-derived factor (PEDF) protein in bronchial epithelial cells (BEAS-2B). Methods Human BEAS-2B were subcultivated, followed by low, medium and high concentrations of PM2.5 (25μg/ml, 50μg/ml, 100μg/ml) stimulation for 24 hours. The expression of PEDF protein in supernatant was ana-lyzed by enzyme-linked immunosorbent assay (ELISA), and the expression in BEAS-2B cells was detected by Western blotting. Results Compared with the control group, the expression of PEDF protein in supernatant and BEAS-2B cells induced by PM2.5 (25 μg/ml) in-creased, but no significance was found (t=-0.730, t=-1.840, P>0.05), and the expression induced by PM2.5 with the concentrations of 50μg/ml and 100μg/ml significantly increased (t>5.798, P<0.05). Conclusion PM2.5 with the concentrations of 50μg/ml and 100μg/ml could increase the expression of PEDF protein in a concentration-dependent manner both in supernatant and BEAS-2B cells.
RESUMO
Acupuncture is an important method to cure diseases in TCM.which has been extensively accepted.Acupuncture manipulation is a key point for good clinical curative effect because different manipulations can bring out different organic reactions.The author summarized clinical experience on acupuncture manipulations for acupuncturists to improve medical effects.
RESUMO
Objective To observe therapeutic effects of acupoint catgut embedding therapy on ulcerative colitis.Methods 55 cases of ulcerative colitis were randomly recruited into a treatment group and a control group. The treatment group was treated with catgut embedding, and the control group was treated with oral administration of salicylazosul fapyridine. Results The therapeutic effect of the treatment group was better than those of the control group (P=0.002＜0.05). Conclusion Acupoint catgut embedding therapy has a better therapeutic effect on ulcerative colitis.
